QT113A-ISG Integrated Circuits (ICs)

The QT113A-ISG is a capacitive touch switch developed by IDEC Co., Ltd., which is capable of turning on or off an electrical appliance in response to a single press, or touch. The device incorporates a built-in physical and electronic design featuring an IC circuit, electrostatic capacitance type operation and an integrated transistor to provide reliable operation, stable performance and a very accurate switching action. This capacitive touch switch is used in applications that require single-touch operation or toggle-style operation for controlling lighting, audio/video systems, and other electrical applications.The operating principle of the QT113A-ISG relies on a change in the electrostatic capacitance of the user’s finger that is detected by the device’s sensing surface. When a user’s finger makes contact with the sensing surface, their electric charge modifies the capacitance of the device’s sensing surface and a signal is sent to the integrated transistor. This signal is then amplified and transmitted to the output terminal, which completes the circuit and turns the device on or off.The QT113A-ISG is highly reliable and is capable of withstanding harsh environmental conditions as well as temperatures ranging from -10°C to +45°C. The device features a solid state design and a robust operating life of 10 million cycles, making it suitable for long-term use in harsh industrial applications. Additionally, its integrated transistor allows for a variety of signal outputs ranging from 2 A (at 12 VDC) to 4 A (at 250 VAC).The QT113A-ISG offers a variety of other advantages, including noise immunity, which helps to ensure a more reliable and accurate switching action; an intuitive design; and cost-efficiency. The device can also be used with a range of optional accessories, such as release dampers, spring-loaded actuators, and noise reduction elements to further improve the user’s experience.This IDEC Co., Ltd. capacitive touch switch is designed for a variety of industrial applications, including factory automation and control, PLC inputs, switches for control panels, and switches for home appliances. In addition to its reliable operation and simple operating principle, the QT113A-ISG is also easy to install and requires minimal maintenance. This makes it an ideal choice for applications that require durable, reliable, and efficient switching operation.
